Given numbers are 686,482,983,847,143
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 686,482,983,847,143 is 255636815434.
Find LCM of 686,482,983,847,143 with Prime Factorization
2 | 686, 482, 983, 847, 143 |
7 | 343, 241, 983, 847, 143 |
11 | 49, 241, 983, 121, 143 |
49, 241, 983, 11, 13 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 11 x 49 x 241 x 983 x 11 x 13 = 255636815434
Therefore, the lowest common multiple of 686,482,983,847,143 is 255636815434.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
686 x 482 x 983 x 847 x 143 = 39368069576836
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
686 : 1, 2, 7, 14, 49, 98, 343, 686
482 : 1, 2, 241, 482
983 : 1, 983
847 : 1, 7, 11, 77, 121, 847
143 : 1, 11, 13, 143
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 686,482,983,847,143, is 1.
Now, the common factors can be found like this.
686:2x 7x 7x 7
482:2x 241
983:983
847:7x 11x 11
143:11x 13
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 11 = 154
Therefore, the value for common factors is 154.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 39368069576836/(1x154)
LCM = 39368069576836/154
LCM = 255636815434
Thus, we can understand that the LCM of 686,482,983,847,143 is 255636815434.
